-Web servers accept incoming connections by listening on port 80 by default. Type "netstat -an" from a command prompt.

for example:

# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses (0.0.0.0)

#Listen 12.34.56.78:80
#Listen 80
Listen 888
